Mining has been a valuable component of the Canadian economy for more than a century and will continue to be so for the foreseeable future. The most significant producers include oil sands, coal, base and precious metals, uranium, potash and diamonds. Land requirements for the management of mine waste are often enormous and difficult for lay people to comprehend. The Canadian Council for Innovation in Mining recently declared there is an urgent need to reduce the land and water footprints associated with mine waste impoundments. In addition, the oil sands industry wishes to reduce long term liabilities associated with fluid containment by moving from wet tailings systems towards dry landscapes. Achievement of these objectives will require the construction of elevated mine waste repositories with positive topographies that offer water shedding characteristics.

采矿业是加拿大经济的一个重要组成部分，已有世纪之久，在可预见的未来仍将如此。最重要的生产商包括油砂、煤炭、贱金属和贵金属、铀、钾肥和钻石。管理矿山废物所需的土地往往是巨大的，外行人难以理解。加拿大采矿业创新理事会最近宣布，迫切需要减少与矿山废物蓄水池有关的土地和水足迹。此外，油砂行业希望通过从湿尾矿系统向干地转移来减少与流体容纳相关的长期负债。实现这些目标将需要建设高架矿山废物处置库，具有良好的地形，提供排水特性。
